If you love cookies that are crisp on the outside and soft and nutty inside, these flourless walnut cookies are about to become your new favorite. I’ve tested this naturally gluten-free recipe several times to perfect that light, airy texture and rich walnut flavor — all with just a handful of simple pantry ingredients. They’re dairy-free and taste just like classic European walnut meringue cookies from a specialty bakery.
But for me, they’re even more special. One bite instantly takes me back to my childhood in Bulgaria, where my grandma made these for us and called them “orehovki.” That nostalgic walnut aroma is something I’ll never forget.
Ingredients You’ll Need
One of my favorite things about this recipe is how short and simple the ingredient list is.
- Egg whites – These create the airy structure. Make sure they’re at room temperature for better volume. Avoid any yolk traces, or they won’t whip properly.
- Powdered sugar – I use regular powdered sugar here, but you could also substitute it with powdered coconut sugar or powdered light brown sugar.
- Walnuts (finely ground and coarsely ground) – The finely ground walnuts form the base of the cookie and give it structure, almost like a flour replacement. The coarsely ground walnuts add that irresistible rustic texture and bite. I’ve tested this both ways, and using two textures truly makes a difference. When grinding at home, pulse carefully – stop before the nuts turn into walnut butter.
- Cinnamon, pure vanilla extract & a pinch of salt – The cinnamon adds warmth, the vanilla deepens the sweetness, and the salt brings out the rich walnut flavor. I never skip it – it truly makes a difference.
How to Make Walnut Cookies
- Prepare Your Oven. Preheat your oven and line your baking sheets with parchment paper. Don’t skip the parchment — these cookies are delicate while warm.
- Whip the Egg Whites. In a clean, dry bowl, beat the egg whites until stiff peaks form. You’ll know they’re ready when the peaks stand straight up when you lift the beaters.
Tip from experience: If your bowl has any grease residue, the egg whites won’t whip properly. - Add the Sugar Gradually. With the mixer running, slowly add the powdered sugar a few tablespoons at a time. This step builds a glossy, stable meringue. Beat until the mixture looks smooth and shiny.
- Add Flavor & Finely Ground Walnuts. Mix in the finely ground walnuts, cinnamon, vanilla, and salt. Beat on low just until combined, about 1–2 minutes.
- Fold in Coarsely Ground Walnuts. Switch to a spatula and gently fold in the coarser walnut pieces. This keeps the mixture airy.
- Scoop & Bake. Scoop rounded portions onto the prepared baking sheets, leaving a little space between each. Bake until the tops look set and lightly golden. Let them cool on the baking sheet before transferring – they firm up as they cool.
TIPS FROM NELI’S KITCHEN
Top Tips for Perfect Walnut Cookies
After testing these several times, here are the things that truly make a difference:
- Room temperature egg whites whip better.
- Add sugar slowly – rushing this can deflate the meringue.
- Don’t overmix after adding nuts. You want to preserve air.
- Use two textures of walnuts. This is the biggest flavor upgrade.
- Let them cool fully before moving – they’re fragile when hot.
- For a crispier cookie, bake an extra minute or two.
- For a softer center, pull them out right at the 10-minute mark.
Storing
These cookies store surprisingly well.
- Room temperature: Store in an airtight container for several days.
- Freezer: Freeze in a single layer, then transfer to a container. Thaw at room temperature.
- Avoid humid environments — moisture softens the crisp exterior.
Serving Suggestions
These cookies are especially popular as gluten-free holiday cookies, but I honestly bake them year-round. Here’s how I love serving them:
- With afternoon coffee or espresso – I especially love these with a rich pour over coffee or a creamy bulletproof coffee. And if I’m in the mood for something a little indulgent, my fluffy dalgona coffee alongside these walnut cookies feels like a café-style treat at home.
- Alongside hot tea – When I’m craving something lighter and soothing, I’ll pair them with warm lemon tea, ginger tea, or a spiced chai tea latte. The cinnamon and walnut flavors complement those cozy teas beautifully.
- As part of a holiday cookie platter
- Drizzled lightly with melted dark chocolate
- With a scoop of vanilla ice cream for contrast
They also make a beautiful edible gift — just stack them in parchment-lined boxes.

It stole the show.
I love hearing that! So glad these walnut cookies were a hit! 🙂
I made these today and they were delicious! I had to make one change, I didn’t have powdered coconut sugar, so I used 1/2 cup powdered monkfruit and a 1/3 cup granulated coconut sugar, and then last minute I decided to add a dash of cloves. They reminded me so much of oatmeal cookies, just so good! Next time I’ll add some raisins. But I’ve already eaten more than I should, they are really tempting!
So glad to hear that you loved them! The addition of cloves sounds delicious!
I’m doing an anti-inflammatory diet where I can’t have any sugar or sugar substitutes, but fruit is allowed. So for sweetness I added raisins and dates to the walnuts when I ground them up. My first batch needed twice as many dates, but otherwise, they turned out really tasty. I also used the whole egg.
Can i use honey instead of sugar for this recipe?
Hi! I haven’t tried it with honey and I am not sure if it will work because honey is liquid and coconut sugar is not. Let me know how it turns out if you try it with honey.
Thanks for such a great but super simple recipe. I was looking for a way to get more walnuts into my diet, and this is it! After reading Gabriela’s comment, I only put in 1/2 cup coconut sugar and it was enough. After reading Renee’s comment, I just ground all of the nuts coarsely and used 2 whole eggs instead of egg whites, and it all held together beautifully without the flour. Yummy!
Very tasty and so easy to make! But, I will add only half a cup of coconut sugar next time, since it’s too sweet. I used 1cup and it was still too sweet, but yammy. Maybe the recipe ment to say 1/3 cup of c sugar not 1 1/3 cup?
These walnut cookies look wonderful. I would love to have a few with a cup of coffee or tea. Yum!
Yes, they go wonderfully with a cup coffee, and even with a cup of milk. 🙂
Thanks for stopping by!
These walnut cookies look amazing. Perfect treat! Oh goodness!!
Thanks, Sabrina! Glad you like them!
Your paleo walnut cookies looks delicious. I never tried any cookies without flour, I think I can use your recipe to try it. By the way the watch looks really nice.
Thanks, Swathi! Hope you give this recipe a try, I think you will love it!

Hi! Thanks for the recipe! I just made these and I wanted to ask you how you made these w/o adding any flour. I had to add about a cup of coconut flour to my batter before I was able to form cookie balls. The final cookie is amazing but definitely needed the coconut flour to be able to form the balls.
Hi Renee, so glad you liked these! You could just use a little bit more ground walnuts if you think the batter was too runny.
